To all whom t may concern,

Be it known that I, JOHN H. CoRNLIsoN, a citizen of the United States,residing at the city of St. Louis, in the State of Mis-l souri, haveinvented a certain new and useful Swinging Window-Screen, of' which thefollowing is such a full, clear, and exact description as will `enableany one skilled in the art to which it appertainsto make and use thesame, reference being had to the accompanying drawings, forming part ofthis specication.

The object of my invention is to produce a swinging window screen whichwill be as simple as possible in construction and vhence will not onlybe easy to manufacture and low in costbut which will also be reliable inaction and not likel to get out of order.

A further object o my. invention is so to construct a screen that it maybe made in half lengths and reversed so as to be applied to either thelower or the upper half of the window frame.

In the accompanying drawings, which illustrate some forms of screen made1n accordance wlth my 1nvent1on, Flgure 1 1s a vertical central sectionof a window frame provided with my preferred form of screen; Fig. 2 is aslightly enlarged view of the upper part of Fig. 1 showing the screenreversed; Fig. 3 is an enlarged section on the line 3 3 of.Fig. l; Fig.4 is a view similar to Fig. 1 but showing the full length screen; Fig. 5is an'enlarged view of the upper portion of Fig. 4; Fig. .6' is asection on the line 6 6 of Fig. 4; Fig. 7 is an enlarged view showing amodification in which the screen is placed between the blind partingstrips; Fig. 8 is a view showing means for yieldingly supporting thescreen without springs; Fig. E) is a section on the line 9 9 of Fig. 7,and Fig. IOis a section through the lower part of the screen showing amodification.

Like marks of reference refer to similar parts in the several views ofthe drawings.

15 is the window frame which is provided with a lower sash 16 slidingbetween guide strips 17 and 18 and an upper sash 19 sliding between theguide strip 18 and the blind parting strips 20.

In my preferred form of screen, as shown in Figs. 1, 2 and 3, the screen21 is arranged to hear against blind parting strips 20. The end of thescreen 21 which is at the top when the screen is in the position 'upper'in Fig. 5 of the drawings.

shown *in 1 is provided vwith a filling strlp 22 which is of greaterthickness than the remalnder of the screen and this filling strip 22 isprovided with bearings 23.adapt' ed to engage with pins 24 in the blindpart? ing strips 20' at a point slightly above the middle of the windowframe. In order to hold the screen in position against the pins 24sprmgs 25 are provided, one end of each of sald springs being secured tothe screen 21 at its central point and the other being 'adapted toengage with a hook 26 inthe blind parting s trip adjacent to the bearingpms 24. It willbe evident that the tens1on of the spring 25 will holdthe screen in position. against these bearing pins and at the same timelallow the lower end of the screen to be swung outwardly.

In order to allow for the reversal of the screen so that it maybe usedat the upper part of the window frame, I place adjacent to thetransverse blind parting strip aprojection or strip 27 leaving a recess28 adapted to receive the end of the screen opposite "to the fillingstrip 22, as is showny in Fig. 2.

Adjacent to these recesses 28 is a hook 29 adapted to be engaged withthe end of the spring 25 so that the same spring may be used to hold thescreen in place` in either position. As the lower sash of,.a Window issomewhat longer than the upper, the pins 24 will come in such a positionas to miss the lling strip 22 when the screen is in its position, asshown in Fig. 2 of the drawings. In Figs. 4, 5 and 6 I have shown amodification in which a screen 30 is made the entire length of thewindow frame and hence can not be reversed. It is held in position insubstantially the same manner as the screen 21 when in the positionshown in Fig. 2. In this modification, however, it is not necessary-tohave a spring which extends to the central portion of the screen as thespring is not reversed. Consequently I use a short spring 31 `as shownin detail the length of the screen 30 it is desirable to have means forsecuring the lower end of4 it in position when it is not desired to openit and consequently I provide it with a re taining hook 32, as shown inFig. 6.

On account of"v In Fig. 7 of the drawings I have shown i a modificationin which a screen 33, in place of fitting agamst the blmd partmg strips20, is arranged between such strips so that v is 'obtained a blind maylbel used in'eonjunetion withthe screen@ -f I'n,f order to:l allow" this,aperturesf'3'4 are "formed inthe 'upper rail of the-` screen and throughtheseL apertures pass wires 35 attached to-'sprin'gs 36 'which 'arethismodification the screen is beveled at its upper end as shown at-40 andis provided with a pin 41 adapted to engage with 'a suitable aperture inthe upper portion of the window frame. As will be seen from Fig. 8 ofthe drawings, the -screen is Amade slightly shorter in this constructionso that it may move upwardly as 1t 1s swung outwardly at the bottom. Inplace of the spring 31 I use a wire 42 secured to the screen and to thehook 29. It will be evident that in this construction the weight of thescreen itself furnishes the yielding means for holding it in positionand that the pin `41 retains it against accidental displacement.

In `Fig..10 I have shown a modification which is useful in connectionwith the form of screen shown in Fig. 7 which lies between -the blindparting strips. In order to allow for the fastening of the blinds 43 thelower portion of this screen is cut away at 44 so as to admit access tothe fastening hook 45 of the blind. This-cut away portlon 44 is coveredby a board 46 which is secured in position by means of pins 47 in thebottom of the window frame and detachable hooks 48.

I-Iaving vfully described my invention, what I claim as new and desireto secure by Letters Patent of the United States is:

l.- In combination with a window frame,

" a swinging screen, longitudinally extensible springs' permanentlyfastened at corresponding ends to the inner face of the screen and theirother ends pivotally connected to and readily detached from the frame,allowing the entire screen to be moved away from the frame and held inparallel or oblique planes thereto, said springs serving, when undertension, to hold `one edge of the screen in revoluble contact with theframe and normally holding the inner -face of the screen -yieldinglyagainst `the frame, as set forth.

2.-In combination with a window frame, a swinging screen, longitudinallyextensible springs loosely connected at corresponding ends to the innerface of the screen and to said frame, allowing theentire screen to bemoved away from the frame and held in parallel or oblique planesthereto, said springs serving, when under tension, to hold one ledge ofth, iscreenfrevolublyfin contact with the frame and normally'ho'lding4the inner face of the screen yieldinglyagainst the 3. The combinationwith'a window frame, provided with a projection at its upper end andwith bearing pins, of 4va screen, one end of which'vis adapted toengage'fwith'fsaid projection kwhenathe'screen is in one position andthe other end of which is adapted to engage with said. pins' when thescreenis in another position.

4. The combination with a window frame provided with a projection atvits upper end andwith bearing pins,"of a screen, one end of which is'adapted to engage with said p'rojection when the screen is in oneposition4 and the other end of which is adapted to engage with said pinswhen the said screen is in another position, and yielding means forholding said screen in posltion.

5. The combination with a window frame, provided with a projectionatitsupper end and with bearing pins, of a screen, onev end ofwhich isadapted to engage with said projectionwhen the screen is in voneposition and the other end of which is adapt-ed to engage with said pinswhen the screen is in another position, and spring means for yieldinglyholding said screen in position.

6. The combination with a window frame provided at its upper end with aprojection upon the frame at one end and at the intermediate point withbearing pins, of a screen, one end of which is adapted to engage with'said projection whenthe screen is in one position and the other end ofwhich is adapted to engage with said pins when the screenis in anotherposition, and a spring secured at one end to said screen and adapted tobe se-- cured at the other -end adjacent both to said projection and tosaid pins.

7. The combination with a window frame provided with a projection atitsupper end and with bearing pins, of a screen, one end land the otherend of which is adapted to engage with said pins when the screen vis inanother position, and a spring-secured at one v end near the center ofsaid screen and adapted to be secured at the other end adjacent to bothsaid project-ion and to` said pins. y

8. The combination with a window frame.

provided at its upperk end with a projection i and at a point above-itscenter with bearing pins, of a screen of more than half the length ofsaid frame, one end Yof said screen being adapted to engage with saidprojection and the other with said bearing pins.V

v 9. The combination ywith a window frame provided at its upper end witha projection and at a point above its center with bearing pins, of ascreen of more than lhalf the length of said frame7 one end of saidscreen being adapted to engage with said projection and the other beingprovided with a filling piece of a thickness approximately equal to theWidth of the outer parting strip of the Window frame and adapted toengage :with said pins, and yielding means for securing said screen inbot-h its upper and lower position.

10. The combination with a window frame provided at its upper end With aprojection and at a point above its center with bearing pins, of ascreen of more than half the length of said frame, one end of saidscreen being adapted to engage-with said projection and the other beingprovided with a fillingpiece of greater thickness than the remainder ofthe screenv and adapted to engage with said pins, and a spring securedat one end to the center of said screen and adapt-ed to be securedatythe other end adjacent both to said pro-4 jection and said pins.

In testimony whereof I have hereunto set my hand and atlxed my seal inthe presence of the two subscribing Witnesses.
